What this shows Kaltech's Innovation Score is 36.6/100 (top 46% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Kaltech?

Each dot is one of Kaltech’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Kaltech’s own 3.3 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kaltech's grants concentrate

Kaltech Corporation is a focused PatentsView assignee: 5 CPC subclasses with 33.3% of grants classified under A61L (Methods OR Apparatus FOR Sterilising Materials OR Objects IN GENERAL; Disinfection, Sterilisation OR Deodorisation OF AIR; Chemical Aspects OF Bandages, Dressings, Absorbent Pads OR Surgical ARTICLES;). By volume, Kaltech sits between Kaha PTE. Ltd. and Kanazawa University.

Kaltech's three-year grant acceleration

Kaltech Corporation shows 6 grants in 2022–2024 against only 0 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
